Abstract/OtherAbstract:

Purpose: To compare the influence of aerobic and resistance exercise on intraocular pressure (IOP). Methods: Twenty-one healthy subjects participated. Aerobic exercise was performed using a cycle ergometer, and resistance exercise was performed with a leg curl and a butterfly machine. Intraocular pressure was measured at baseline, during exercise and 10 min after. During resistance exercise, a Valsalva manoeuvre was prevented. Results: Before aerobic exercise, the mean IOP was 18.8 ± 2.7 mmHg. It was 16.5 ± 2.8 after 10, 17.1 ± 2.6 after 20 and 16.7 ± 3.3 mmHg after 30 min of exercise. After 10 min, the IOP returned to baseline (18.8 ± 2.7 mmHg). The mean IOP before resistance exercise with the leg curl machine was 17.0 (15.6-18.4; 65%W(max) ) and 16.8 (15.3-18.3) mmHg; 75%W(max) ) and did not change significantly during the experiment. The mean IOP before resistance exercise with the butterfly machine (65%W(max) ) was 16.4 (15.2-17.6) and increased to 17.2 (16.0-18.4) mmHg (p < 0.05). After 10 min of recreation, it recovered to 16.3 (15.0-17.5) mmHg. At 75%W(max) , the mean baseline IOP was 16.3 (15.2-17.4) mmHg, and there were no significant changes. Conclusions: Aerobic exercise leads to a significant decrease of IOP. There was no influence of resistance exercise on IOP as long as a Valsalva manoeuvre was prevented.
